Described quick press down system depresses by two that motor drives inlet side respectively and outlet side is depressed leading screw, and the described Motor Shaft end of depressing is equipped with hydraulic clutch.
The working roll that described five roller rollers are device adopts two times three arrangement, and top working roll has the big guide plate of inlet; The bottom working roll of outlet side is independently installed.
Described highly efficient cooling device comprises: have working roll inner cold water system, the outer cooling of the constant voltage injection system of swivel joint, and the circulating cooling system of walking beam.
The utility model is a device because the utility model adopts five roller rollers compared with prior art, and the spacing between the working roll is big and all do not have backing roll, therefore, efficient cooling system can be set.Like this, can be between rolling mill and quickly cooling device, the steel plate of 700~1100 ℃ of high temperature is carried out continuous pre-straightening.Simultaneously, have the following advantages and beneficial effect:
1, can guarantee the reliability service of equipment by efficient cooling system;
2, can quick and precisely set the straightening process requirement of satisfying the different size steel plate to roll gap by quick press down system;
3, the independent adjustment by outlet roller position, limit effectively improves steel plate leveling effect end to end;
4, the fast roll changing device can be that device is changed fast to five roller rollers, has effectively shortened equipment downtime;
5, through the hot steel plate of pre-straightening machine, can effectively be discharged the internal stress that in the operation of rolling, produces, simultaneously, the steel plate glacing flatness effectively improves, thereby after having guaranteed that steel plate enters fast cooling device, the uniformity and the uniformity of steel plate cooling have increased substantially the product lumber recovery.
